Cleaning a used mouthpiece

I am buying a used mouthpiece metal.
I was told by a drummer that to clean/sanitize it,
he would put some salt in boling water and let the mouthpiece boil for a few minutes. He said it would not affect the finish, but would sanitize any germs with the salt.
Then brush is inside and out with soap and rinse.
Will this ruin the finish on a mouthpiece metal or any other comments.. Thanks
